🚀 DEPLOYMENT PROCEDURES

Production Deployment Checklist

Pre-Deployment (T-24 hours)

# 1. Backup current state
./scripts/backup-production.sh --full

# 2. Verify staging environment
./scripts/verify-staging.sh --comprehensive

# 3. Run security scan
./scripts/security-scan.sh --production

# 4. Check resource availability
kubectl top nodes
kubectl top pods -A

# 5. Validate Mainnet RevenueRouter deployment record mode
cd digitalia-contracts
npm run validate:mainnet-planned
npm run validate:revenue-policy
npm run validate:service-pricing
npm run validate:revenue-production

Deployment record mode policy:

  • Pre-launch phase: validate:mainnet-planned is the required gate.
  • Post-launch phase: switch to validate:mainnet-deployment and require strict pass.
  • Do not mark production-ready if strict mode is required and failing.

Deployment Process

# 1. Enable maintenance mode
kubectl apply -f k8s/maintenance-mode.yaml

# 2. Deploy new version
kubectl set image deployment/digitalia-dvm dvm=digitalia/dvm:v1.2.0
kubectl set image deployment/digitalian-passport passport=digitalia/passport:v1.2.0

# 3. Wait for rollout completion
kubectl rollout status deployment/digitalia-dvm --timeout=600s
kubectl rollout status deployment/digitalian-passport --timeout=600s

# 4. Run health checks
./scripts/health-check.sh --production

# 5. Disable maintenance mode
kubectl delete -f k8s/maintenance-mode.yaml

Rollback Procedure

# Emergency rollback
kubectl rollout undo deployment/digitalia-dvm
kubectl rollout undo deployment/digitalian-passport

# Verify rollback
kubectl rollout status deployment/digitalia-dvm
kubectl get pods -l app=digitalia-dvm

Blue-Green Deployment

Setup Blue-Green Infrastructure

# Create green environment
kubectl create namespace digitalia-green

# Deploy to green
kubectl apply -f k8s/ -n digitalia-green

# Test green environment
./scripts/test-environment.sh --namespace digitalia-green

# Switch traffic (update ingress)
kubectl patch ingress digitalia-ingress -p '{"spec":{"rules":[{"host":"digitalia.org","http":{"paths":[{"path":"/","pathType":"Prefix","backend":{"service":{"name":"digitalia-service-green","port":{"number":80}}}}]}}]}}'

🔧 TROUBLESHOOTING GUIDE

Common Issues & Solutions

1. DVM Node Not Starting

# Check logs
kubectl logs -f deployment/digitalia-dvm

# Common causes and solutions:
# - Insufficient memory: Increase memory limits
kubectl patch deployment digitalia-dvm -p '{"spec":{"template":{"spec":{"containers":[{"name":"dvm","resources":{"limits":{"memory":"16Gi"}}}]}}}}'

# - Corrupted blockchain data: Restore from backup
./scripts/restore-blockchain-data.sh

# - Network connectivity: Check service discovery
kubectl get endpoints digitalia-dvm

2. High Block Time

# Check validator status
curl -X POST http://digitalia-rpc:8545 \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","method":"digitalia_getValidatorInfo","params":[],"id":1}'

# Check network latency
kubectl exec -it digitalia-dvm-0 -- ping digitalia-dvm-1.digitalia-dvm.digitalia-production.svc.cluster.local

# Solutions:
# - Scale up validator nodes
kubectl scale statefulset digitalia-validators --replicas=6

# - Optimize consensus parameters
kubectl patch configmap digitalia-config -p '{"data":{"consensus.timeout":"5s"}}'

3. Database Connection Issues

# Check database connectivity
kubectl exec -it digitalia-dvm-0 -- pg_isready -h postgres -p 5432

# Check connection pool
kubectl exec -it postgres-0 -- psql -U digitalia -c "SELECT * FROM pg_stat_activity;"

# Solutions:
# - Increase connection pool size
kubectl patch configmap postgres-config -p '{"data":{"max_connections":"200"}}'

# - Restart database connections
kubectl rollout restart deployment/digitalia-dvm

Performance Issues

Memory Leaks

# Monitor JVM heap usage
kubectl exec -it digitalia-dvm-0 -- jcmd 1 VM.summary
kubectl exec -it digitalia-dvm-0 -- jcmd 1 GC.run

# Heap dump analysis
kubectl exec -it digitalia-dvm-0 -- jcmd 1 GC.dump /tmp/heap.hprof
kubectl cp digitalia-dvm-0:/tmp/heap.hprof ./heap.hprof

# Analyze with Eclipse MAT or similar tool

Disk Space Issues

# Check disk usage
kubectl exec -it digitalia-dvm-0 -- df -h
kubectl top nodes

# Clean up old logs
kubectl exec -it digitalia-dvm-0 -- find /logs -name "*.log" -mtime +7 -delete

# Expand persistent volumes if needed
kubectl patch pvc blockchain-data -p '{"spec":{"resources":{"requests":{"storage":"2Ti"}}}}'
